a WALL OONSTRCTION.

'Apiicafi'on ned June s, 19127. seriai No. 197,466.`

My invention lis a Wall :construction made ofgtiles, blocks, bricks: or the like. y An object ,oi my invent-ion is a wall constructionfniade oitl tiles, vblock or bricks, each formed angular or someyvh'at- L- struction tvi'th' blocks `'as above 'describech 'thereby giving Ian air space between lthe tivo iaces of the Wall.

, l V further objecty of my invention is a block or tile for Wall construction formed somewhat `I -fshaped in cross..v section,V the short arm forming a transverse part of the block 'andV having a cnt-out section. The blocks are'also lformed `Wilt-,h corrugationson 'the edges, which intert with adjacent blocks,-.. y

Another Object of my invent-ion is the construction., of a mold for forming the blocks, and the inet-bod.ofhmolding.A y Y 'Y My invention Will be more readily understood from theV following description and drawings, yin which: Y f Y Figure 1 is a perspective view of a. Wall lconstructed in accordance `with Amy Vinvention. Figure 2V isa vertical .transverse section on fthe line 2-2 'of Figure-1,111 the direction ofthe arrows. Y Y" Figure 3 is a vertical'ljongitudinal'section of partof thetvall on the line 3--3 of Fig. 2, inthe direction ot th'earrows., Figure 14 is a perspective View of one Ot theblocksl f 'Figure 5isa .plan vieiv of the mold for .forming th'e blocks.

. Figure 6 is ,a longitudinal section through the mold on 'the line 6 6 of Fig. 5, in the direction of vthe arrows. e v The;particular block or tileforming a feature ot my invention is substantially asvfollows, being designated generally by the numeralll: I

This tileV is formed angular or L-shaped andhas onearm V12 forming alng arm, and 'another arm 13 forming a transverse arm.

VThe end edge 14 of the long arm is preferably; vcorrugated with longitudinal corrugat-ions, and the end face 15,01- the short arm 13 is also preferably corrugated With longitudinal corrugations. The .L-shaped, arm 13 has recessed or cut-out sectionrlf forming in effect lugs 17'I at each end of the block on` the arm, 'The fiatvface 18` of the block, being the side of the long arm, rforms the outside face or'finished side of the block.

The iside face 19 ofthe arm 13, forms an' l inside face of the block as does also therside A2O of the long arm 12. The block lis so constructed ,that thefmeasuremei'it 21 from the lower edge 15 tothe upper surface of the lug 17 is' one-half the measurement 22 between the edges 14 and '1 5.y Thev .lugs-'17 may eX- tenl any Adesired distance from the end of vthe block.

The manner of building {up a Wall in ac,- cordance with my invention is substantially asiollowsz-m.l .l vf.. i n Having reference .particularly to Figures 1, 2 and, 3, in ivhich casea loyver block 23V is formedby 'breakinga com-plete block at the level kot' the top ofthe lug 17, or by forming' a Aspecial block. Adjacent thereto, .an Opposite block24 is constructed on a base Vor .foundation 25 With edge 141 downwardly and the edgel up, With the face 18vforming a finished face of the Wall. lThe-"short arm 13 l of thisbIOOk overlaps the edge v15 of the block 23, these blocks being set 'apart so that there is a space 26 between the blocks. An-

other comple'te block 2Tisb`ui'l't-,up 'on the other sideV of the Wall., thee'd'ge 14-iit'ting 'on the edge 15 of the block 2 3 and With the face 18 outwardly. Thisblock has the lugs 17 `substantially engaging the` edge 15 of the block 24,. leaving a space 28. .The lmeeting .and joining edges of the blocks are secured by ordinary mortar or by cement mortar', and, ifv desired, longitudinal Are-'e'nforcin-g bars 29 may be, imbedded in the-mortar, preferably the layer of mortar on topof the edgel 15gof each of the blocks. By this construction, a zigzag air passage 30 is .formed between the'blooksgformi'n'g the two sides 'ofv the Wall, this zigzag vpassage.being formed by the space sections'26 and28betvveent-he blocksand tjhespacelft bythe recessed .or cut-outseotion 16 ofthe shortarm 13fofthe block.A The blocks are preferably builtupjto break jointas'shofwvn in Fig. 1, ywhich shows thefrec'ess 16 as .forming apart'offfthe air space in a transverse direction, the spaces i 26 and 2S forn'iing the air space in a vertical in this manner, the blocks being preferably olis-ct to forni the spaces aboveA mentioned, where it is desired to forni a wall with air .spaces between the two sides. If a solid wall is desired, these spaces betvveen the blocks maybe lilled with cement or the like, with or Without re-venforceinent, and if desired the blocks may be placed close together Vso that the inside surface 19 of the blocks on one :eide of the Wall lfgubstantially contact with the surface il() of the l'ilocks on the Vother side of the Wall, and mortar may be placedbetiveeii these tivo surfaces forniing an additional binding of the Wall. T he blocks Ainayalso be built up forming any suitable type of joints, either broken as illustrated in Figi, or in any ofthe various.

types of join-ts used in brick Work or in block or tile construction.

The mold for making the blocks is constructed .substantially as follows:

As illustrated in Figures and 6, th-ere are a pair of opposite side-boards and a plurality of -full height transverse boards 136 and a plurality of substantially half height boards 37. Blocks 38 are litted between and .secured to boards 36 and 37, and bolts 39vinay be utilized to secure the assembly comprising` the boards 36, 37 and the blocks o8, lto the side-boards 35. Strips of sheet metal such as galvanized iron 40 are secured to the upper edge 4l of the half height boards 37 and to the upper edge 42 of the 'blocks 38, the sideedge 43 of this metal strip abuts against the side of each of the boards 36. 'l1 he boards 36 are completely corrugated on one side 44 and are partly corrugated on the other side, as indicated at 45. The outside surface 46 of the half height boards 37 is also corrugated.

`The recessed oreut-out section l'of the lblocks is formed by inserting Wood lillers, or

the like, 47, ivhich preferably have a beveled end 48, rin the space between the sides 44 of the boards 36 and the sides 4b' of the boards 36. Covering part of suoli latter boards, a

K strip of fabric 49 or other suitable material is secured to the fillers 4T and extends over the sheet metal strip or covering 40. ,The Whole mold as built up is supported on a base l550. 1

The manner of molding the blocks is substantially-as follows:

`When the mold is assembled as above described, itv is preferably coated with some material which will prevent adherence Vof concrete or cement, such as by a coating of kerosene or some light oil, and the ,cement is molded in the open space and, if desired,

tions be secured by bolts 39, as these can be i spaced the desired distance apart and the friction holds them in place when the cement is molded in the proper manner `in order not to disturb 'the spacing. However, there` should be a suliicient number of these bolts to hold the assembly in a solid position. These bolts may be disconnected and the sideboards 35 removed, then the mold parts, starting at one end, can be removed one at a time, the blocks taken out and the liller pieces 47 disconnected from the blocks, leav-V ing a finished cement block substantially as .shown in Fig. 4.

From the above description, 1t will be seen that I have developed a lnovel type of block which may be utilized to make a Wall con#l struction as illustrated in Figures 1 and 2, with the angular or Lshaped blocks inter- 'itting from oppositesides of the Wall; and this construction may be utilized to make a hollen7 or solid wall, as desired. I have also developed a mold suitable for making such blocks, the method of molding blocks having the above characteristics. It is to be understood that the blocks may be made in any suitable manner and if desired these "may be of a clay product molded by suitable maf cliinery and burnt in kilns, or the like.

Various changes maybe made in the principles of my invention Without departingfrom the spirit thereof, 'as set forth in th description, drawings and claims. i f Iclaim: y y l. A building block substantially L-shaped iir'ei'oss section, one arm ofthe L having al cut-out section adjacent the inner angle of the L with lugs at each end of such arm, the thickness of such arin at thelugs being sub-` stanti ally half that of the ividth of the'other arm, and the said block havingf corrugated upper and loiver edges. i

2. A Wall construction comprising in comv lbinatioii a plurality of vL-shaped blocks, each block `having `aii'arin forming part of the wall face, one edge of said arm being corrugated, the other arm of the L forming'a transverse part of the wall and having a cut-out section between end lugs, the thickness of the transverse arm at the lugs being substantially halt the width ofthe face arm and said transverse arm having corrugations liti opposite the said Vcorrugated edge, and cev yinenting material binding the blocks.

p o. A building block of general 'L-shaped section definedv as having a! vertical branch et the L. and horizont/a1 branch, @shore zontal branch having horizontal lugs at each end and a depressed or cut-out section hav-y ing a horizontal top surface, the vertical measurement 'of the through the lugs being substantially half that of the vertical branch.

4. A building block substantially L-shaped in cross-section defined as having a vertical branch with ribs on the top horizontal surface and a horizontal branch With ribs onk the lower horizontal surface, said horizontal horizontal branchV In testimony whereof I have signed my name to this specification.
